Business Framework Implementation

Conclusion

This chapter has applied the concepts from Chapter 1 to implement about a third of the framework discussed in Chapter 2. At this point, the framework provides enough functionality for a business developer to build object-oriented systems that support useful concepts such as the following:

• N-level undo

• Validation rules

• Authorization rules

• Data binding

• Change tracking

• Strongly typed collections

• Editable and read-only objects

• Root and child objects

Chapters 4 and 5 will finish the business framework. Chapter 4 will focus on implementing the data portal concept and supporting object persistence. Then Chapter 5 will wrap up by implementing a variety of functionality to support a business developer in building an application using mobile objects.

From Chapter 6 on, the focus will be on designing and building a simple business application that illustrates how the classes in the framework can be used to build applications based on mobile business objects.
